A frictionless ramp of mass m2 is initially at rest on a horizontal frictionless surface. A small box of mass m1 is placed at the top of the ramp and then released from rest. After the box is released, it slides down the ramp and onto the horizontal surface, where it is measured to have a speed v, having fallen a total distance h?
